Diabetes Medicine Pulled Over Carcinogen Concerns

The Food and Drug Administration has posted the voluntary recall of another metformin—the ninth brand pulled since May. Riomet ER, a Type 2 diabetes medicine marketed by Sun Pharmaceutical, was found in tests to contain too much N-nitrosodimethylamine, a carcinogen, the Miami Herald reports. The recall applies to Lot AB06381: 500mg tablets of metformin hydrochloride labeled for extended-release oral suspension, with an expiration date of October 2021. The FDA posts a roundup of its NDMA announcements here. (NDMA also was a concern when retail chains dropped Zantac last year.)
